This product worked exactly as advertised. It replaced a sail switch that had failed and is working fine. Of particular note is the vendor "Plumbing Planet". Plumbing Planet was very responsive and helpful when I contacted them. I would rate Plumbing Planet as a very good vendor.Get more detail about Honeywell S688A1007 sail switch, SPDT, with plastic sail for EAC control. Mounts in the return duct..
